‘You never see that guy in the gym,’ an insider spilled.

It’s no secret Jonah Hillhas dropped a significant amount of weight since his pudgy Superbad days, but sources say the actor owes his new slimmed-downed figure to lap band surgery. “You never see the guy in the gym,” an insider spilled. “He claims to eat sensibly, but NOBODY drops that kind of weight without some kind of help.”

Sources insist that “help” came from a gastric lap band. Before-and-after photos show the five-foot-seven actor smashed the scales at a whopping 260 pounds, sources said. Hill, 33, used to sport a much rounder figure, but the comedian is now down to a svelte 175!

The star was seen swimming in a football jersey that seemed too huge for his radically reduced framed.

The lap band wraps round the top of the stomach,” weight loss expert and book author J.J Flizanes, who has not treated Hill, said. “It squeezes the stomach, reducing it in size and limiting the amount of food you eat. Its supposedly safer than gastric bypass surgery.
